Although silicate of soda or other silicates and albumenare water-soluble or water-miscible colloids other water-miscible or watersolublecolloidal substances may be added to the ingredients of my herein disclosed composition or to the components thereof.

While I have herein described some particular compositions embodying my invention and methods of producing the same and also mentioned some of the arts in which my invention may be utilized, it is to be understood that the invention is not limited to those arts, or to the precise methods, ingredients or proportions mentioned.

- Having thus described my invention, I claim and desire to protect by Letters Patent of'the United States:

1. An adhesive composition comprising;

normally water-resisting flexible elastic gum colloid, blood albumen and a water-soluble silicate. 4

2. An adhesive composition comprising a. normally water-resisting flexibleelastic gum colloid, blood albumen and sodium silicate 5. An adhesive composition in aqueous dispersion comprising rubber-latex, blood albumen andsodium silicate;

7. An adhesive composition in aqueous disrsion comprising rubber latex, blood alumen, sodium silicate and an alkali.

8. An adhesive composition in aqueous dispersion comprising rubber, blood albumen,

and a water-soluble silicate.

9. An adhesive composition in aqueous dispersion comprising rubber, blood albumen, a water-solu le silicate and an alkaline stam bilizini medium.

10. n adhesive composition in aqueous dispersion comprising rubber latex, blood albumen, ammonia, and a water-soluble compound of silica.

15 In witness whereof I have set my hand this 19th day of July, 1927.
